Protein Electrophoresis, Serum With Reflex to IFE, Serum and Free κ and λ Light Chains, Serum

This test measures specific proteins in your blood, including immunoglobulins and light chains, to check for abnormal patterns. It helps show whether your immune system is producing an excessive amount of a single type of protein, which can indicate a disorder of the plasma cells in your bone marrow. Doctors use these results to investigate symptoms like unexplained bone pain or fatigue and to screen for conditions such as multiple myeloma. However, this test alone cannot provide a final diagnosis and usually requires additional testing to confirm the specific cause of any abnormalities.
